Application April 9, 1937, Serial No. 135,926 7 4 Claims.

As the title of this invention would-indicate, the device of thisinvention relates to means to adjust windows, that is, to adjust thedegree of window opening and to provide means to keep the window inadjusted position.

There area number of devices now on the market, which are designed toaccomplish the broad objects of the device of this invention, however,in all of the contemporary adjusters of which applicants have knowledge,complicity, fragility and cost are objectionable characteristics, whichtaken together with awkwardness ofoperation, forbid their satisfactoryuse, and it is with this thought in mind that we have conceived thedevice of the present invention and have reduced it to commercial form.

Therefore, with the foregoing as a premise, it may be stated that theobject of the present invention is to provide a window adjuster which issimple in construction, easy to operate, rugged and reliable, and of lowcost.

Other objects, features and advantages may appear from the accompanyingdrawings, the specification and the subjoined claims.

In the drawings, of which there are two sheets:

Figure 12 is a. view partially in section, as taken on line l2--|2,Figure 11, showing the device of this invention in installed position.

Figure 13 is plan View of the adjustable bar of this invention.

The device of this invention, as indicated by the reference character isadapted to co-operate'with a swingable window 22, to efiect openingorclosing thereof through various degrees of adjustment.

The window 22 is mounted upon hinges 24 in a 10 frame 26, in the usualmanner, andas is usually the case with this type of window, a screen 28is placed across the inner face of the window in the manner shown inFigure 2.

The adjuster bar of this device comprisesa 15 length of flat, flexiblesteel 30, provided with groups A and B of teeth or notches 68 in thelower edge thereof, while a finger grip or handle 32 is provided uponone end of the bar. Openings 34, through which screws 36 may beinserted, are formed in the opposite end portion of the bar 30.

That portion of the bar which is secured to the rail 38 by means ofscrews 36, is adapted to lay flat thereagainst, while at a pointindicated by the reference character 44, the bar is bent outwardly atapproximately 60 degrees, as shown in the drawings. The remainder of thebar is straight, its end, as above stated being provided With a fingergrip or handle 32, not only as a matter of convenience, but also as amatter of finish.

A slot 46 formed in either the lower rail of the screen 28, or in amember 48, of similar dimension, is adapted to permit the bar to moveback and forth therethrough. A face plate 50 is Well adapted to coverthe slot formed in the member 48, and also serves to guide the bar as itmoves back and forth in following the window 22. The slot or guide 52 isenlarged at 54 to provide clearance for the teeth or notches 68 as thebar 30 bends in moving through its path of travel. The face plate issecured to the window sill 56 by means of screws 58, while a keeper 6!]having a base member 5|, a vertical leg 62, and an overhanging lip 64,is adapted to hold the bar 38, and to prevent its protruding into aroom, where it might otherwise interfere with curtains, blinds, etc.

The lower interior edge of the enlargement 54 43"? is positioned abovethe base 66 of the face plate to provide a latch 15 which is slightlyhigher than the depth of the teeth 68, in order that the bar 30 may beable to use the full depth of the teeth to effect a locked connection,and also to prevent the bar from scraping or otherwise marring thefinish of the base 66.

Details of window construction do not enter It will be apparent that byclosely spacing the teeth, we are able to provide practical means toaccommodate windows having jambs of varied ,width.

Outwardly from tooth group "A, the notches are spaced to provide varyingdegrees of window opening adjustment, as indicated by notch grouping B,see Figure 8.

It will be noted that the bar 30 is provided With a slight bend 40,which extends across the width thereof, (see Figure 8) the purpose ofwhich is as follows. In securing the bar 30 to a window,

that part of the bar indicated by the reference character 4| is laidparallel with the rail 38 of the window, and is of course held inposition by screws 36, thereby projecting the handle portion 32 in adownward direction because of the 'bend ii! which directs the handleportion at a tangent to that portion of the bar which is secured to therail 38 of the window. The purpose of this construction is to firmlymesh the teeth or notches with the latch l5, and to remove the'necessity for hand placement of the bar, or the teeth thereon, inengagement with the latch, for as constructed, the bar willautomatically engage the latch 75, unless prevented from doing v so, byupward pressure on the handle portion thereof.

To use the device of this invention, it is only necessary to follow theprocedure to be now described. Assuming the window to be in closedposition as shown in Figures 9 and 11, it is only necessary to removethe bar from under the lip of the keeper 83, whereupon the bar swings tothe approximate position shown in Figure 2. The bar is now lifted tofree the teeth or notches 68 from engagement with the latch 75, and isthen thrust outwardly, thereby causing the window to also swingoutwardly.

After the desired amount of window opening is obtained, the bar 30 isreleased, thereby causing the notch or tooth 68 most nearly to theproper degree of opening to rest astride the latch 15 of the face plate50, thereby securing the window in open, locked position.

The total number of teeth or notches 68, and

the exact gradations thereof on the bar 30 may be varied to meet thegeneral average of Weather conditions in any given part or section ofthe country, or to meet the individual requirements of the propertyowner, without departing from the spirit of the invention.

From the foregoing description it will be apparent that we have provideda cheap, reliable, rugged, simple and highly efiicient window adjuster.

It is obvious that various changes and modifications and variations maybe made in practicing the inventionin departure from the particularshowing of the drawings and description, as given, without, however,departing from the true spirit of the invention as defined by the scopeof the appended claims.
